    摘要: Probes labeled with 1,2-dioxetane precursors can be employed in a variety of assays. The probes may be nucleic acid, peptide nucleic acid, proteins including enzyme, antibody or antigen, steroid, carbohydrate, drug or non-drug hapten. The probe is provided with a 1,2-dioxetane precursor bound thereto, generally either covalently, or a strong ligand bond. The dioxetane precursor moiety is converted to a bound 1,2-dioxetane by exposure to singlet oxygen. These dioxetane (labels) either spontaneously decompose, or are induced to decompose by an appropriate trigger to release light. The trigger may be a change in pH temperature, or an agent which removes a protective group. Assay formats in which these 1,2-dioxetane labeled probes and referents may be used to include hybridization assays, immuno assays, gel-based assays and Capillary Zone Electrophoresis.

    摘要: The present invention discloses multiple enzyme assays which measure the activity of at least one endogenous enzyme in a single aliquot and a method of measuring the activity of multiple enzymes in an aliquot of a cell extract, wherein at least one of the enzymes is an endogenous enzyme. In one embodiment of the invention the activity of a first enzyme is quantified by measuring the light signal produced by degradation of a first enzyme substrate by the first enzyme and the activity of the second enzyme is quantified by measuring the light signal produced by the degradation of a second substrate. In the method of the present invention, both quantifications are performed on the same aliquot of cell extract. Different embodiments of the present invention provide for the detection of more than one endogenous enzyme and for the detection of at least one reporter enzyme and at least one endogenous enzyme. The present invention also discloses kits for detecting the activity of multiple enzymes.

    摘要: An interventional medical closure device comprises a first engagement element for engagement with an external surface of a vessel on a first side of an opening through the vessel wall and a second engagement element for engagement with an external surface on a second side of the opening. A closure element extends from the first engagement element, into the vessel, and to the second engagement element to assist in closure of the opening. The device may include a foot element to engage the internal surface of the vessel on both sides of the opening. The foot element may provide a guide with a pathway for the closure element.

    摘要: Methods and apparatus for characterizing composite materials for manufacturing quality assurance (QA), periodic inspection during the useful life, or for forensic analysis/material testing. System are provided that relate eddy-current sensor responses to the fiber layup of a composite structure, the presence of impact damage on a composite structure with or without a metal liner, volumetric stress within the composite, fiber tow density, and other NDE inspection requirements. Also provided are systems that determine electromagnetic material properties and material dimensions of composite materials from capacitive sensor inspection measurements. These properties are related to the presence of buried defects in non-conductive composite materials, moisture ingress, aging of the material due to service or environmental/thermal exposure, or changes in manufacturing quality.
